Images won't load on webpage. Where am I going wrong?

Hi, I'm a noob. Most of what I have learned so far has been working except for adding an image using CSS. This is really frustrating.

Details:

I'm using a Mac, Snow Leopard, Text Wrangler, and or Komodo. html file is on desktop, as is image. Ive tried different file extensions for the image, I've tried adding quotes around the photo file that lies within the parentheses.

yea, spaces in file names or even in file paths can cause lots of problems [and stress] for those trying to deal with them.
If you still want to break the file name up, I suggest using - or _ between the words, but, not spaces.
